I. Product Positioning
TheK7V63Sis a hydraulic main oil pump designed bySany Heavy Industryfor concrete pump trucks, categorized as anaxial piston pump. It is widely applied in critical hydraulic drive modules such as the boom system and pumping system of Sany pump trucks. Its core function is to provide stable and efficient power for the concrete pump truck's placement boom (Boom), ensuring precise extension, rotation, and continuous concrete delivery under high-load conditions.

II. Technical Characteristics
1. High-Pressure & High-Efficiency Design
• Rated Pressure: Typically up to35MPa(some models support higher pressures), meeting demands for high-rise construction and long-distance pumping.
• Flow Range: Adaptable to different pump truck models, with flow rates covering120–240L/min, supporting multi-stage variable adjustment to match varying construction scenarios.
• Variable Control: Utilizes electro-hydraulic proportional control technology for stepless flow regulation, enhancing boom movement smoothness and response speed.
2. Structure & Materials
• Piston-Type Design: Single-stage piston structure ensures stability and durability under high pressure.
• High-Strength Alloy Steel: Pump body and key components use fatigue-resistant, wear-resistant materials to withstand harsh construction environments.
• Sealing Technology: Incorporates imported seals to reduce internal leakage, improve volumetric efficiency, and extend service life.
3. Compatibility & Modularity
• Universal Interfaces: Highly compatible with Sany pump truck hydraulic systems, supporting quick replacement and maintenance.
• Modular Design: Integrable into pump truck models with varying boom lengths (e.g., 37m, 48m, 52m), offering flexible customer adaptation.
------
III. Application Scenarios
1. High-Rise Construction
• Supports vertical pumping heights exceeding180 meters, meeting ultra-high-rise concrete delivery requirements.
• 360° boom rotation enables precise multi-angle placement, minimizing construction blind spots.
2. Large-Scale Infrastructure
• Ideal for bridges, tunnels, and hydraulic projects, supporting high-flow, high-pressure continuous pumping.
• Multi-section folding boom design adapts to complex terrains and narrow spaces.
3. Industrial & Commercial Projects
• Enhances efficiency in factory construction and commercial complexes through flexible boom extension/retraction.
• Diesel-hydraulic hybrid power system reduces energy consumption, suitable for remote or off-grid areas.
